Abstract
The aim of this study was to verify the optimum temperature for germination and the effect of storage time on the emergence of Heteropteris tomentosa . The experimental design was made in randomized blocks with three replications of 100 seeds and the following temperatures: a) 5°C; b) 10°C; c) 15°C; d) 20°C; e) 25°C; f) 30°C; g) 35°C; h) 40°C and j) 45°C. The other experiment was made in a completely randomized design with five replications and the following treatments: a) freshly collected intact seeds; b) freshly collected wingless seeds c) intact seeds with 15 months of storage, d) wingless seeds with 15 months storage. Germination occurred only at temperatures of 25°C, 30°C and 35°C. The optimum temperature for seed germination was 30°C. Wingless H. tomentosa seeds stored for 15 months showed faster and concentrated emergence within the first eight days after sowing.
